getErrorHandler

public ErrorHandler getErrorHandler()

getParallelModificationLock

public Lock getParallelModificationLock()

getExclusiveModificationLock

onTheFlyRebuild

public LuceneBackendResources onTheFlyRebuild()

Creates a replacement for this same LuceneBackendResources: reuses the existing locks and executors (which can't be reconfigured on the fly), reuses the same Workspace and ErrorHandler, but will use a new LuceneWorkVisitor. The LuceneWorkVisitor contains the strategies we use to apply update operations on the index, and we might need to change them after the backend is started.

Returns:

the new LuceneBackendResources to replace this one.
